Wales developer seeks builder for 1.2-MW Ramsey Sound tidal project

Wales-based Tidal Energy Ltd. invites applications for pre-qualification to build its 1.2-MW prototype tidal stream power project in Ramsey Sound off the Pembrokeshire coastline in Wales. Responses are due April 15.

Tidal Energy plans to launch a single DeltaStream device with installed capacity of 1.2 MW deployed for 12 months beginning in June 2012. The project is to include a subsea cable, an onshore control room and substation, and electrical infrastructure to connect with the local distribution network.

The DeltaStream unit includes three horizontal-axis turbines on a single 30-meter-wide triangular frame. The triangular frame is to provide a low center of gravity that allows the unit to sit on the seabed with no positive anchoring or seabed drilling. The base technology previously was developed by Tidal Hydraulic Generators Ltd.

The developer seeks a contractor for Stage 2 development, the final design, construction, deployment, and testing of the DeltaStream device. The contractor is to manufacture, assemble, and deliver the
DeltaStream device to shore side, including integration and assembly of components such as turbine blades, gear hubs, generators, drive trains, cabling, and ancillary components.

The contractor also is to be responsible for manufacture and assembly of a steel frame with the three turbine nacelles.

A pre-qualification questionnaire may be obtained until noon April 12 by e-mail request to Tidal Energy plans to select a short-list of from three to 10 firms to be invited to bid.

Responses are due by noon April 15. For information, contact Tidal Energy Ltd., Vision House, Oak Tree Court, Mulberry Drive, Cardiff Gate Business Park, Attn.: Chris Williams, CF23 8RS Cardiff, United Kingdom; (44) 2920730912; E-mail:; Internet:
